Refer to pump Service Manual for repair procedure and additional technical information.

All High Pressure Systems require a primary pressure regulating device (i.e. regulator, unloader) and a secondary pressure relief device (i.e. pop-off valve, relief valve). Failure to install such relief devices could result in personal injury or damage to pump or property. CAT PUMPS does not assume any liability or responsibility for the operation of a customer’s high pressure system.

Read all CAUTIONS and WARNINGS before commencing service or operation of any high pressure system. The CAUTIONS and WARNINGS are included in each service manual and with each Accessory Data sheet. CAUTIONS and WARNINGS can also be viewed online at www.catpumps.com/cautions-warnings or can be requested directly from CAT PUMPS.

INSTALLATION

An integral Regulator comes with each .MIST pump to provide system pressure regulation and pump protection.

OPERATION

Set the regulator while the high pressure system is turned on. Adjust the adjusting cap in small increments until the desired system pressure is reached. Install a pressure gauge close to the manifold head of the pump to check pressure during start-up and periodically to monitor system performance.

System should be purged of air before operation. System liquid must flow through the pump without discharge restriction to assure full system pressure is reached.

SERVICE

The regulator should be serviced on the same schedule as the seals in the pump.

1. Remove hex adjusting cap, spring and spring setainer.

2. Using a socket or wrench, remove piston retainer from the unloader body.

NOTE: Loctite® 242® is used in the assembly process.

3. Using a needle nose pliers, pull the complete assembly, piston stem through valve from the unloader body.

4. Using caution, grasp the valve with a pliers near the top next to the valve retainer and unthread the piston stem using a flat head screwdriver.

5. Remove o-rings from valve retainer, and back-up-ring and o-ring from piston stem. Examine o-rings and back-up-ring for cuts or wear and replace as needed.

6. Examine the valve, valve retainer and piston stem for wear and replace as needed.

NOTE: The seat will be damaged during removal and must be replaced.

7. Replace seat and stem from repair kit.

8. Lubricate all o-rings for ease of installation and install on seat, piston retainer, valve retainer and piston stem.

9. Assemble the washer, valve retainer with o-rings and valve onto the piston stem with o-ring and back-up-ring and thread together hand tight. Press complete assembly into body until completely seated.

10. Apply Loctite® 242® to threads of piston retainer with o-ring. Thread into body and tighten using a wrench.

11. Insert spring retainer and spring into the body.

12. Thread the adjusting cap into the body and set for system pressure.

NOTE: If unit is infrequently used or periodically stored, o-rings may become dry and will need to be replaced.
